Fun Facts
- 🌱 The flowers are pollinated by hummingbirds in their native tropical habitat and have evolved their distinctive fish-like shape to attract these precise pollinators.
- 🌱 Goldfish plants are epiphytes in nature, meaning they grow on trees rather than in soil, which explains their preference for well-draining, airy growing media.
- 🌱 The plant's genus name, Nematanthus, means 'thread flower' in Greek, referring to the thin flower stems.
